Hmm, there is a problem, though.  If we attempt to avoid a stack
overflow in `apply' by using the heap rather than the stack to store
large numbers of arguments, those arguments are invisible to the
stack-marking gargbage collector.

One workaround is to temporarily disable garbage collection if using the
heap.  Stefan, any ideas?
